So basically a hostile, unknown website asks you to install software on your system with elevated privileges, and if you willfully go through the entire install process (including entering your administrator password) something bad will happen.

Scary.

In other news, if someone sends you an email that says to run sudo rm -rf / on the command line (and enter your admin password when it asks you to) — don’t do it. Interesting attack method — send someone malicious software and ask them to install it as administrator. The defense? Don’t install it.

Make no mistake — this is not the same kind of threat that we’ve faced in Windows over the years. That threat is very specifically the drive-by installation of software without the user knowing or having a chance to stop it.

In summary, this social-engineering-based attack requires a high level of interaction and it will have very little impact on the Mac user community.:
